3D Planet in Captain Blood

[reidrac]

Captain Blood is a beautiful game that has always fascinated me; not only because the story and the gameplay, but also technically.

For example, how did they do the 3D planet render on real time?

Does anybody have any clues on how did they pull it out?

it's offset mapping, very few CPU time with a small texture
like this
you precompute displacement according to angle then you pick in the texture with an offset (and the planet turn around)
